It is evident that we have in this passage a different bird from the Sparrow that sitteth alone upon the house-tops; and though the same word, _tzippor_, is used in both cases, it is clear that whereas the former bird was mentioned as an emblem of sorrow, solitude, and sadness, the latter is brought forward as an image of joy and happiness. "Blessed are they," proceeds the Psalmist, "that dwell in Thy house: they will be still praising Thee.... For a day in Thy courts is better than a thousand. I had rather be a doorkeeper in the house of my God, than to dwell in the tents of wickedness." According to Mr. Tristram, this is probably one of the species to which allusion is made by the Psalmist. While inspecting the ruins in the neighbourhood of the Temple, he came upon an old wall. "Near this gate I climbed on to the top of the wall, and walked along for some time, enjoying the fine view at the gorge of the Kedron, with its harvest crop of little white tombs. In a chink I discovered a sparrow's nest (_Passer cisalpinus_, var.) of a species so closely allied to our own that it is difficult to distinguish it, one of the very kind of which the Psalmist sung.... The swallows had departed for the winter, but the sparrow has remained pertinaciously through all the sieges and changes of Jerusalem." The same traveller thinks that the TREE SPARROW (_Passer montanus_) may be the species to which the sacred writer refers, as it is even now very plentiful about the neighbourhood of the Temple. In all probability we may accept both these birds as representatives of the Sparrow which found a home in the Temple. The swallow is separately mentioned, possibly because its migratory habits rendered it a peculiarly conspicuous bird; but it is probable that many species of birds might make their nests in a place where they felt themselves secure from disturbance, and that all these birds would be mentioned under the collective and convenient term of Tzipporim.

Only in two instances is the word CUCKOO found in the Authorized Version of the Bible, and as they occur in parallel passages they are practically reduced to one. In Lev. xi. 16 we find it mentioned among the birds that might not be eaten, and the same prohibition is repeated in Deut. xiv. 15, the Jews being ordered to hold the bird in abomination. It is rather remarkable that the Arabic name for the bird is exactly the same as ours, the peculiar cry having supplied the name. Its habit of laying its eggs in the nests of other birds is well known, together with the curious fact, that although so large a bird, measuring more than a foot in length, its egg is not larger than that of the little birds, such as the hedge-sparrow, robin, or redstart.
